If a vertical line, within the domain of the function, intersects the graph in more than one points, it is not a function.
The domain of a function is simply the x values of the function
Find the maximum and minimum values that the function can take over all the values in the domain for the input. The range is the maximum minus the minimum.
The "x values that work are the domain numbers like for y=x+1 would be any real number. But, y= sqrx x would have to be non-negative.
The domain is a subset of the values for which the function is defined. The range is the set of values that the function takes as the argument of the function takes all the values in the domain.
A number does not have a range and domain, a function does.
The domain of a function determines what values of x you can plug into it whereas the range of a function determines the values that are your results. Therefore, look at the y-axis if you want to determine the range of a function and look at the x-axis if you want to determine the domain.
Assuming the domain is unbounded, the linear function continues to be a linear function to its end.

No, when the domain repeats it is no longer a function
Find the maximum and minimum values that the function can take over all the values in the domain for the input. The range is the maximum minus the minimum.
Domain of the logarithm function is the positive real numbers. Domain of exponential function is the real numbers.
The "x values that work are the domain numbers like for y=x+1 would be any real number. But, y= sqrx x would have to be non-negative.
The range of -sin x depends on the domain of x. If the domain of x is unrestricted then the range of y is [-1, 1].
The diagram should be divided into to parts, the domain and the range. The domain is those things that you put into the possible function and the range is what comes out. Let's call a member of the domain x and of the range y. You can tell it is a function by tracing from each x to each y. If there is only one y for each x; there is only one arrow coming from each x, then it is function!
